Trivia

The Japanese word for lid (蓋, futa) is pronounced almost the same as the Japanese word for pig (豚, buta). After certain sounds, the f-sound becomes a b-sound, as is the cases in the name of this technique, making the two homophones. The lid created with this technique is shaped like a pig or a boar, making the name a pun.
